Solution
To verify the identity
we start with the left side and use the power-reducing formula for
:
Now, we rewrite the left side:
Next, we will rewrite this expression by multiplying the numerator and denominator by
:
Now, we distribute
in the numerator:
Thus, we have:
So, the expression we have after multiplying and distributing is:
This is the expression we were looking for, and we can see that it matches the right side of the original identity:
Thus, we have verified the identity. The final answer for the expression after multiplying and distributing is:

To verify the identity, start with the left side
. Using the power-reducing formula, we have:
Next, when you rewrite this expression and multiply both the numerator and denominator by
, it looks like this:
Now, distribute
in the numerator:
So we have:
This confirms our original identity as true!
